STEAM BOILER OPERATION & MAINTENANCE MANUAL
IMPORTANT: With each boiler, the Manufacturer furnishes a complete set of Installation Instructions
for the Installer and a complete set of Operation & Maintenance Instructions for the owner. Instructions for the
owner includes a plastic enclosed Operating Instructions and the Operation and Maintenance Manual. BE
SURE THE OPERATION & MAINTENANCE INSTRUCTIONS ARE LEFT FOR THE OWNER. These
instructions should be kept near the boiler in a protected place available for quick reference.
INSTALLATION: In order to receive the best results from the boiler system, it is essential that the boiler
be properly installed and correctly operated. Be sure to review the Guide on Proper Installation and Boiler
Operation. The General Basic Installation Instructions, Specific Installation Instructions with Drawings #1 and
#2, the Floor Plan Drawing and Specification Sheet are excellent guides to proper installation. The Installation
Check-off Sheet and Final Check-off and Start-up Sheets should be properly filled out to be certain that all
items of installation have been properly performed.
OPERATION: Before operating the boiler, carefully review the Operating Instructions and the Burner
Control System. Be sure that the installation conforms to Manufacturer's Standards and that the electrical and
fuel supply are correct as specified. Do not attempt to start boiler without reading the Operating Instructions.
On the initial lighting of the boiler, remove the cabinet door and test the boiler for safe ignition and proper control
operation. Each boiler has been factory fire tested, but all burners and safety controls should be carefully
checked and tested because of possible change due to shipping vibration. Be sure the low water cut-offs
safely shut off the fuel supply on low water. Before putting the boiler into service, blowoff the boiler several
times until the boiler water is clean.
MAINTENANCE: The Manufacturer is sincerely interested in each Parker Boiler installation and wishes to
co-operate in every way possible so that the best in operating life and efficiency will be experienced. A proper
Water Treatment, Blowoff and Maintenance Program must be provided to assure a successful long life
operation. Each boiler is furnished with two water sample bottles and we urge each customer to send an initial
sample for analysis and recommendations and another sample once the recommended water treatment
program has instituted. This service is provided at no charge to the customer. For water treatment
recommendations, see Bulletins 1001-B and 1002, and 101-5DD. A proper Boiler Blowoff Program is
necessary and should be performed in accordance with the Boiler Blowoff Instructions. The Weekly
Maintenance Report and Quarterly Inspection Report serve as excellent guides for the recommended periodic
maintenance.
APPROVALS: Your boiler has been furnished in accordance with Standard Code Requirements and a
Manufacturer's Data Report is mailed to you under separate cover. If this has not been received, immediately

SEQUENCE OF OPERATION
GB6 OR GC6 CONTROL SYSTEM WITH M1R OR RM7890
PARKER-LITE SEQUENCE INDICATOR & INTERRUPTED PILOT
I. CONTROL POWER ON:
With the electrical switches turned "On", the indicator light "Control Power on" should be on. This
indicates electrical power to the boiler controls and that the boiler is ready for operation.
If this does not come on, check switches, fuses or circuit breakers, improper electrical supply, broken,
loose or dirty electrical connections. If a door interlock is furnished, be certain the boiler control panel
door is tightly shut so that door interlock is energized.
II. WATER SAFE:
With the control power on a circuit to the water control is energized. If there is a safe water level in the
boiler, the "Water Level Safe" indicator light will turn on. NOTE: If a manual reset type low water cutoff is
used, it may first be necessary to reset the control before the light will turn on.
III. LIMIT SAFE:
With power on, and water level safe, the circuit to the limit controls is energized. The gas cock at the gas
inlet must be open to energize the low gas pressure switch and it must be manual reset. If the
temperature (or pressure) in the boiler is below the high limit setting and the gas pressure is within the
setting of the high and low gas pressure switches, the "Limit Safe" indicator light will turn on. The high
limit and gas pressure switches may require manual reset if they cycle off.
IV. PILOT ON AND BURNER ON:
With power on, water level safe, limit safe, and the main burner switch on, a circuit is energized to the
operating control. If the operating control is calling for heat, the circuit to the flame safeguard is
completed and the following sequence takes place:
BURNER STARTUP
1. Pilot valve and ignition transformer are energized from flame safeguard through interrupted pilot time
delay relay. "Pilot On" indicator light will be on.
2. Pilot flame must be proven within 10 seconds or pilot and ignition will turn off and safety lockout will
occur within 15 seconds. If a safety lockout alarm is furnished, it will sound.
3. If pilot is proven, the main electric gas valves are energized. Pilot and ignition turn off. "Pilot On"
indicator light will turn off. Main burner flame must be proven or lockout occurs. "Burner On"
indicator light will be on.
4. Burner operates until heat demand is satisfied.
BURNER SHUTDOWN
1. Burner turns off when operating control is satisfied. Electric gas valves close.
2. The "Pilot On" and "Burner On" light will be off and the other lights will remain on. If other indicator
lights are not on, the highest light off indicates which failure has caused the boiler to safely
shutdown.

BURNER CONTROL SYSTEM GC6
PARKER GAS FIRED STEAM OR HOT WATER BOILERS
FIREYE M SERIES WITH MP560 OR MEP560 PROGRAMMER OR
HONEYWELL RM7895C SERIES FLAME SAFEGUARD WITH INTERRUPTED PILOT
1. FLAME SAFETY SYSTEM:
The Flame Safety System consists of a Flame Safeguard (Fireye M Series with MP560 or MEP560
programmer or a Honeywell RM7895C with a flame rod to provide instant automatic 100% shutoff on
pilot-main flame failure. The electronic combustion safeguard control is especially designed for
instantaneous flame detection. Flame supervision is provided by the flame rod in an exclusive electronic
flame rectification circuit wherein short circuits or grounds cannot simulate the presence of a flame.
Whenever the boiler is firing, the pilot or main burner flame is supervised. Should a flame failure occur,
the main burner is instantly shut down within 4 seconds. The system then goes out on safety lockout
and the button on the flame safeguard must be manually reset (with power to the control) before the
boiler may be restarted. During operation, whenever the operating control or any safety or limit control
breaks its circuit, the main burner turns off. On the next call for heat, the pilot will automatically ignite and
once it is safely proven by the electronic control, the main burner will turn on. After 10 seconds, the pilot
and ignition will automatically turn off and the Flame Safeguard will supervise the main burner flame.
2. IGNITION SYSTEM:
The Ignition System consists of an Electric Pilot Valve, high voltage Ignition Transformer, and a spark
ignition electrode, which will automatically ignite the pilot. When there is a call for heat, the flame
safeguard energizes the pilot valve and ignition transformer to produce an intense spark, which will
readily ignite the pilot. Once the pilot flame has been safely ignited and proven, ignition ceases and
remains off until the next cycle by the flame safeguard.
3. PILOT BURNER:
A Honeywell Q179 Pilot Burner Igniter and Flame Rod-Sensor is used to automatically ignite the main
burner whenever the gas is turned on and all safety and limit controls are energized. This system
employs an interrupted pilot, which is lighted automatically each time there is a call for heat. The pilot is
turned off automatically after igniting the main burner at the end of the main burner flame trial for ignition
period. It remains off until the next cycle by the flame safeguard.
4. ELECTRIC GAS VALVE(S):
The Electric Gas Valves are electrically operated valves installed on the burner manifold for the purpose
of shutting off all gas flow to the burner except the pilot. The valves are wired for 115 volt, single phase
operation. Both gas valves are wired in series with all the safety and limit controls so that in the event of
low water, pilot failure, main flame failure, electrical failure, or high limit, they will automatically shut off the
main flow of gas, thereby, preventing a hazardous condition from occurring in the boiler. For further
details, see Bulletin on particular valve.
5. LOW WATER CUTOFF:
All Boilers are furnished with a probe type low water cutoff. A separate secondary low water cutoff is
recommended on all boilers and standard on all steam boilers. The low water cutoff is wired in series
with the electric gas valves to shut off the main burner on a low water experience. This control is very
reliable having no moving parts on the water side. If a float type control is furnished, it should be regularly
flushed and cleaned. One manual reset control is furnished. It is necessary to reset this control any time
a low water condition occurs. For further details, see Bulletin on this control.

6. BCS 101-210 GC6
PAGE 2 OF 2
9C
6. LOW WATER ALARM - STANDARD ON 70-150 HP STEAM BOILERS ONLY:
If a Low Water Alarm is furnished, it is wired in conjunction with the low water cutoffs to automatically
sound whenever a low water condition exists in the boiler. The alarm should sound whenever electricity
is applied to the boiler and on steam boilers when there is no water level visible in the gauge glass.
Boilers 70 to 150 HP are furnished with an alarm horn. When required, the same alarm is also used to
indicate "safety lockout" of the flame safeguard. The same alarm is also used to indicate a high water
condition when a high water alarm is required and furnished.
The alarm may be silenced by turning the Main Burner Switch to the "Off" position so that the cause of
the alarm may be corrected. When the alarm is silenced in this manner, the burner will also be turned
off. When refilling steam boilers after blowdown, the main burner switch may be turned off and the boiler
feed pump can be energized without the burner turning on.
7. PUMP CONTROL & MOTOR STARTING RELAY--STEAM BOILERS ONLY:
The Pump Control is wired in conjunction with the boiler feed pump to inject water into the boiler as
required. The pump control energizes the pump until water reaches the normal water level height. The
pump is re-energized any time the water level drops to the pump start level. Boilers 70 to 150 HP are
furnished with two pump controls. The pump controls are wired to first start pump #1 on a drop of water
level and then Pump #2 if the water level continues to drop.
A Pump Motor Starting Relay is furnished as a means of switching on the heavy current load of each
Boiler Water Feed Pump with the contacts available in the water level pump control. If a Pump Motor
Starter with heaters is furnished, be certain that the proper sized heaters are installed to protect the
pump motor from overloads. For further details, see Bulletin 123 MSR.
8. OPERATING & HIGH LIMIT CONTROLS:
All boilers are furnished with separate high limit and operating controls. Steam boilers are furnished with
pressure controls. Hot water Boilers are furnished with temperature controls. See separate Bulletin for
proper setting of these controls.
9. OTHER TRIM:
The Boiler Controls Switch is furnished for convenience in electrically shutting off the boiler controls
circuit. CAUTION--HAZARD OF ELECTRIC SHOCK: The Boiler Controls Switch does not shut off all
electricity to the panel box. A Main Line Disconnect Switch, with fused disconnect or circuit breakers,
must be installed and turned "OFF" whenever servicing the panel.
All Boilers Controls are standard for 115 Volt operation. When 3 Phase pump service (or 230 Volt, single
Phase) is used, a Control Transformer is furnished to reduce boiler control voltage to 115 Volts. The
boiler control circuit is then protected from over-current and short circuits by a circuit breaker or a fuse.
If a door interlock is furnished, it turns off the boiler control circuit whenever the panel door is open. It
does not shut off all electricity to the panel box. Be certain that the panel door is tightly shut so this
interlock is energized or the boiler will not turn on.
WARNING: ONLY QUALIFIED SERVICE PERSONNEL SHOULD ATTEMPT TO STARTUP, ADJUST
OR REPAIR THIS UNIT. NEVER BYPASS ANY SAFETY CONTROL.

STEAM PRESSURE CONTROLS
The steam pressure in the boiler is controlled by adjusting the following controls.
1. High Limit Control – Honeywell L404 Pressuretrol – Standard All Boilers:
The H L404 High Limit Control (16B) is furnished to shut off the main burner if the pressure in the
boiler rises above the setting of the operating control and it fails to operate. The large screw on
top of the pressuretrol is for the pressure indicator setting. This control should be set to shut off
approximately 5 PSI above the operating control (low pressure boilers 14 PSI maximum) and
always at least 10% below the pressure setting of the safety valve. This control is furnished with
manual reset. If this control shuts down the boiler, the operator shall not place the boiler back in
operation until the cause of the shutdown has been determined and corrected. The indicator
settings on all pressure controls are approximations and if a more accurate control is required, the
pressuretrol should be set with a reference to an accurate pressure gage.
2. Operating Control – Honeywell L404 Pressuretrol – Standard All Boilers:
The H L404 Operating Control (16C) is furnished to shut off the main burner if the pressure in the
boiler rises above the desired operating pressure. This control should be set to shut off
approximately 5 PSI above the desired operating pressure (low pressure boiler 13 PSI maximum).
This can be accomplished by setting the "MAIN" pressure indicator (right scale) at these settings
and the "DIFF" differential indicator (left scale) for 5 PSI on high pressure boilers (except on
boilers equipped with A21 regulator, the "DIFF" scale should be set for 15 PSI). On low pressure
boilers the "DIFF" scale should be set for approximately 3 PSI. The pressuretrol will turn off at the
"MAIN" scale setting and turn back on at the "MAIN" setting minus the "DIFF" setting. The shut off
pressure must always be at least 10% below the pressure of the safety valve and be below the
high limit setting. The large screw on top of the pressuretrol is for the "MAIN" pressure indicator
setting and the smaller screw is for the differential indicator setting.
3. Modulating Control – Superior A21B Regulator:
Standard: Atmospheric Gas Fired Boilers 50 HP and Smaller
the control consists of Model A21B Superior Steam Pressure Gas Regulator (7SPGR) installed on
the burner side of the electric gas valve for purpose of modulating the burner flame to
automatically obtain the desired steam pressure. The large adjusting screw on top of the regulator
should be set for the desired steam pressure with the approximate regulation being 5 PSI for each
1/4 turn. The pressure is increased by "screwing in" clockwise and decreased by "screwing out"
counterclockwise. The adjusting screw on the side of the regulator is for the purpose of controlling
the low fire and should be properly set so that all burners stay on low fire when the regulator
reaches its pressure setting. The low fire should never be set below 1" WC. This screw has been
pre-adjusted at the factory and adjustment should not be necessary. If adjustment is necessary,
precaution should be taken to adjust this for a proper minimum flame and care should be taken in
turning this screw, as this is a very sensitive adjustment. Too high a low fire will result in
exceeding the desired pressure setting. Too low a fire will result in lighting problems and
carbonizing of the burner. All lock nuts should be securely tightened after making any
adjustments. For further details, see Bulletin 128.

STEAM PRESSURE CONTROLS
(CONTINUED)
4. Modulating Control – Honeywell L91 Pressuretrol:
Standard: Atmospheric Natural Gas Fired Boilers 70 HP and Larger
Gas/Oil Fired Boilers 16 HP and Larger – Oil Fired 150 HP
The H L91B Modulating Pressuretrol (16E) is wired in conjunction with the modulating gas valve
(7EGM) to control the steam pressure in the boiler by modulating the main burning firing. The
control should be set 5 PSI below the desired operating pressure (low pressure boiler
approximately 10 PSI) by adjusting the "MAIN" scale setting with the large screw on top of the
case. The "DIFF" differential scale (small screw) should be set at "B". The differential scale is
additive. With these settings the boiler will operate on high fire until pressure comes to the main
scale setting. The boiler will then begin to modulate to the low fire setting.* IF the pressure
continues to rise the operating control will eventually turn off the boiler.
5. High-Low Fire Control – Honeywell L404 Pressuretrol:
Standard: Atmospheric Propane Fired Boilers 15 HP and Larger
Oil & Gas/Oil Fired Boilers 16 – 115 HP
The H L404 High-Low Fire Control (16D) is wired in conjunction with the high fire fuel valve(s) to
control the steam pressure in the boiler by reducing the main burner to low fire. This control
should be set at the desired operating pressure (low pressure boiler approximately 10 PSI) by
adjusting the "MAIN" scale setting with the large screw on top of the case. The "DIFF" differential
scale (small screw) should be set for 5 PSI (3 PSI on low pressure boilers). With these settings the
pressuretrol will turn the burner to low fire* at the "MAIN" scale setting and turn back to high fire at
the "MAIN" minus the "DIFF" setting.
6. Operating Control Low Pressure Night Control – Honeywell L404 – Optional:
The H L404 Operating Control Low Pressure (16CLP) may be optionally provided on high
pressure boilers to operate the boiler at low pressure. This control is wired in series with the
operating and high limit controls through a selector switch. The "MAIN" scale is set at 15 PSI and
the "DIFF" scale is set at 10 PSI. With these settings and the selector switch in the "low" position,
the boiler will operate between 5 and 15 PSI on off/on firing. With the switch in the "high" position,
the Operating Control Low Pressure is bypassed and the boiler will operate on its regular operating
controls. The selector switch has a center "Off" position. Always completely turn switch to high or
low position for operation.
NOTE: The above are recommended settings but the actual settings depend upon the load and
operating conditions and should be adjusted in the field for best results to match requirements of
the particular application.
*WARNING:
On Atmospheric Gas Fired Boilers, never adjust the low fire setting of the gas valve below these
minimum values:
Natural Gas - 1" W.C. minimum
Propane Gas - 11" W.C. minimum
These are the minimum safe operating gas pressures at the burner.

WATER TREATMENT DO'S & DON'TS
DO: DON'T:
1. Establish a comprehensive water treatment
program consisting of: soft water, chemical
treatment, monitored blowdowns, regular
water sample analysis & internal tube
inspections.
Assume everything will be OK.
2. Use soft water 100% of the time. Use City water if hardness exceeds 2 grains
per gallon (34.2 ppm).
3. Use a proper Boiler Water Treatment for your
application.
Just read the instructions on the chemical
container, contact the Manufacturer for their
recommendations.
4. Add Boiler Water Treatment by an Automatic
Chemical Feed System. Contact your
Chemical Supplier for their recommendation.
Batch treat chemical as this will not provide
uniform chemical levels in the boiler throughout
operating period.
5. Blowdown boiler to maintain TDS between
2600 ppm (3600 micromhos/cm)-3200 ppm
(4600 micromhos/cm). Partial blowdowns
during the shift should normally be adequate.
If complete blowdowns are required,
complete blowdowns should be made in the
morning or during normal operating period.
Make a complete blowdown at end of operating
period as this may lead to serious oxygen
corrosion problems or leave the boiler dry after
blowdown.
6. Regular Water Analysis at a minimum of once
a month to confirm Water Treatment Program
is correct. Do insist on a monthly Water
Analysis from your Supplier.
Just assume you're doing a good job of
protecting your boiler. The Supplier of your
Boiler Water Treatment will normally test your
boiler water at no charge.
7. Regular internal inspections. Most States
require an annual inspection to determine
what condition the internal water side of the
boiler is in. This is for your benefit and may
prevent expensive repairs.
Ignore inspections even if your boiler is exempt
from Operating Permits and internal
inspections. We would strongly recommend
you do the internal inspection to confirm that
your Water Treatment Program is providing
adequate protection from scale build-up, sludge
accumulation and corrosion failures.
Refer to Bulletin 1001B, 1001C and Blowdown instructions for additional information.

SUPPLEMENTAL INSTRUCTIONS FOR LAUNDRY, DRY-CLEANINGS, OR TEXTILE APPLICATION
Following a proper Boiler Water Treatment Program is essential to ensuring satisfactory performance and durability of
your Steam Boiler System. In order to maintain an appropriate treatment program, the following guidelines should be
adhered to:
1. Use soft water, not to exceed two grains hardness at any time (4 grains hardness if over 50% condensate return).
2. The proper Boiler Water Treatment must be used to prevent corrosion. The Treatment must be able to
maintain a Ph of 10-11.5. Include an oxygen scavenger (Sulfite levels 40-100 PPM) and treat for any residual
hardness. The Treatment should also provide a metal coating ability.
3. The Boiler Water Treatment must be added uniformly throughout the operating day. In any application where "live
steam" is used (i.e. garment presses, etc.), adding chemical once or twice per day will not provide the proper corrosion
protection (batch treating). A proportioning pump or device is required. Boiler blowoffs may be required on a daily
basis. We recommend a total range of 2600-3200 parts per million (or 3600-4600 micromhos/cm), total dissolved
solids (TDS), in order to protect the boiler from sludge accumulation and scale build up. Normally, partial blowoffs
are adequate and should be performed during the beginning of the operating period. However, the number of partial
blowoffs for your particular boiler installation can only be determined by regular boiler water analysis. Should your
water analysis indicate a complete blowoff is necessary, the same should be made at the beginning of the operation.
Important: Complete blowoffs should not be made at the end of the day, as this could cause an oxygen
corrosion failure. Blowing out good, de-oxygenated water at the end of the day and allowing cold, raw, mostly
untreated, aerated water to sit in the boiler during idle periods, only accelarates the process of corrosion.
Typically, in a dry-cleaning, laundry or textile establishment, running a 35-40 hr. work week, would only
require one complete blowoff per week. This is ideally done before the middle of shift on Mondays or at the
beginning of the week. The remainder of the week would then only require the performance of partial blowoffs
before the middle of the shift. Thereafter, blowoffs will be based upon water analysis.
4. Regular Water Analysis of the boiler water must be performed to assure the Boiler Water Treatment Program is
working properly. We recommend a water analysis a minimum of once per month.
5. Internally inspect the new boiler tubing every three months. On new boiler installations, we feel this is very important
to confirm the Treatment Program is appropriate. On a Parker Boiler, the inspection will take less than ½-hour and is
well worth the effort. After confirming proper treatment, refer to Bulletin Qtr. 101-5 for normal frequency.
Today, many businesses that operate steam boilers opt to purchase their boiler chemicals from local supply
companies that service their particular Industry. This may be a very convenient and economical source of supply.
However, in a recent review, we found that for a 9.5 HP boiler, the cost of monthly Boiler Water Treatments through
local supply companies was equal to the annual cost of treatments purchased through a Chemical Manufacturer. In
addition, Boiler Water Treatment companies will provide monthly Water Analyses and Chemical Feed Systems. A
monthly analysis is the only method that will determine if the chemical treatment and program you are using are
correct for your application and boiler system. Also, please note that any failure that is due to an improper water
condition is not covered by any Warranty.
Should you decide to purchase your Boiler Water Treatment from one of your Industry's local supply companies, we
recommend that you inquire about the use of the chemical, the method of adding, and most importantly, be sure to
ask how your boiler water may be tested. In most cases, you will be required to supply the water sample but the
analysis of same will be performed at no charge by the Chemical Manufacturer.
I hope this information proves useful in receiving the maximum life from your newly installed Parker Boiler. With
proper care, I assure you that your steam boiler will provide you with many years of excellent service. If I can help
in any other way, please do not hesitate to call.

GUIDE ON PROPER BOILER OPERATION
PARKER STEAM BOILERS
The Manufacturer has prepared this Bulletin as a Guide for Users of Parker Steam Boilers to Summarize the Basic
Requirements that are necessary for proper Installation, Operation and Long Life Boiler Service. A complete set of
Installation Instructions, Operating Instructions and an Operation and Maintenance Manual are furnished with each Boiler. Be
sure to review these completely and follow Instructions as applicable.
The Parker Boiler is recognized as one of the safest and most economical operating Steam Boilers. The Boiler is known as
one of the least complicated and easiest to operate and maintain. As with any Steam Boiler System, these Basic
Requirements are necessary and must be followed if long life and economical service are to be obtained.
1. PRIOR TO INSTALLATION: Carefully read the General Basic Installation Instructions, the specific Installation
Instructions, Floor Plan Drawings and the Installation Check-off Sheets.
2. PROPER INSTALLATION: Be certain the Boiler is installed in compliance with the prevailing Codes and in
accordance with the Manufacturer's minimum recommendations as outlined in the above mentioned Bulletins.
Installation and operating permits must be obtained from the local Inspection Jurisdiction. Competent installation
personnel should always be used.
3. BLOWDOWN AND DRAIN LINES: Be certain that the Boiler is installed with the required and proper size blowdown
lines and blowdown tank. Since the Parker Boiler may require blowdown at full operating pressure on a periodic
schedule, it is necessary that the blowdown tank and lines not be restrictive.
4. FINAL INSTALLATION CHECK: At completion of installation, the Manufacturer's Installation & Startup Check-off
Sheets should be filled out to be certain that installation conditions are proper before operating the boiler.
5. WATER TREATING PROGRAM: This is one of the most Important Items of Consideration in Boiler Operation.
Carefully review Water Treating Bulletins No. 1001-B & 1001-C.
The Manufacturer recommends the services of local water treating firms that are competent and knowledgeable
providing they comply with the Manufacturer's standards and offer a regular monthly follow-up water analysis service.
The Basic Water Treating Program must include the following:
A. An initial water sample and analysis must be taken of the raw water supply to determine the water treating
program. See Water Sample Instruction 1002.
B. A water softener should be installed in addition to the chemical treatment system if calcium carbonate or
limestone hardness exceeds 3 gpg with no condensate return or 4 gpg with more than 50% condensate
return. Softener should be regularly regenerated any time hardness exceeds one grain per gallon.
C. The proper boiler water treatment should be used consistently, uniformly and adequately as determined from
the water analysis. The boiler water treatment must meet the Manufacturer's standards of Bulletin 1001-B.
The treatment must be used to maintain a satisfactory pH between 10.0 to 11.5. It must include an oxygen
scavenger, provide a protective metal coating and treat for hardness or other conditions determined from the
analysis.
D. The compound must be added in adequate quantities uniformly throughout the shift. An automatic chemical
feed system should be purchased or included with your chemicals so these chemicals are induced into the
feedwater line or the condensate holding tank as recommended by your chemical supplier. We recommend
these chemicals be introduced as far before the boiler as possible to also protect the feed tank and feed lines.
E. The plant should also purchase a conductivity meter and water test kit to be familiar with the treatment and
confirm proper chemical levels in the boiler.
F. Plant personnel should run a conductivity test and sulfite test daily before blowdown until a pattern develops.
A log should be kept to record the data (i.e. Parker Bulletin 1001-C) and filed for future reference. The
blowdown frequency and chemical usage can be set from this information. Once this pattern is developed,
set a pattern of testing for two or three days a week (testing should take a maximum of only 20 minutes).
G. Water sample containers, convenient for mailing, are available upon request. Water Analysis are furnished by
the Manufacturer as explained in Bulletin 1002.
6. BLOWDOWN PROGRAM: The boiler must be blown down as recommended in the Daily Boiler Blowdown Instruction
sheet. Parker Boilers can be either completely blowndown or partially blowndown. The type of blowdown and
frequency of blowdown needs to be set for a particular job based on make-up water conditions, amount of condensate
return, boiler load, and the chemical analysis of the boiler water. An initial blowdown schedule should be
recommended by the chemical supplier and this schedule should be adjusted as necessary based on the chemical
analysis of the boiler water and the water treatment program.

12. BULLETIN 101-5
Page 2 of 2 8C
The total concentrated solids (TDS) in the boiler should be between 2600-3200 PPM (3600-4600 micromhos/cm) and
the blowdowns must be regulated not to exceed this safe limit. Boiler should always be refilled with water after
blowdowns and not left dry. In cold environments, protect boiler from freezing.
7. OPERATING INSTRUCTIONS: The Operating Instructions must be followed as outlined in the Operating Instruction
Sheet.
8. DAILY CHECK ON LOW WATER CUTOFF: The low water cutoff should be checked daily and each time the boiler is
blown down to be certain that it properly shuts off the fuel supply on a low water level.
9. SAFETY CONTROL CHECKS: A regular pattern of checking all the boiler safety controls should be established.
Refer to yearly, quarterly and weekly maintenance report sheets and tune-up sheets.
10. RETURN TANK: The Return Tank and strainer should be inspected every 90 days and cleaned or flushed as
required. This is important to prevent any sediment accumulation from entering the pump or boiler.
11. BOILER WATER FEED PUMP: Burks Pumps do not require packing or lubrication. Current models have sealed
permanently lubricated motor bearings when manufactured. The Mechanical Seal and O-ring should be promptly
replaced if water leaks from the pump around the Motor Shaft. Be certain both check valves are functioning properly
before replacing Mechanical Seal. NOTE: WHEN BOILER IS NOT IN USE IN AREAS SUBJECT TO FREEZING
CONDITIONS DRAIN PUMP AND WATER FEED LINES. BEFORE STARTING PUMP BE CERTAIN WATER INLET
VALVE AND ALL VALVES ON WATER FEED LINE ARE OPEN OR PUMP MAY BE DAMAGED.
12. BLOWDOWN TANK: The Blowdown Tank should be inspected every 90 days and cleaned as required.
13. INTERNAL INSPECTIONS: Internal tube inspections should be made every 60 days until the Water Treatment
Program is properly regulated. This is important so any detrimental tube conditions can be recognized and corrective
measures can be taken to prevent any problems. Thereafter, every 6-12 months or more often if an unsatisfactory
condition is found. This is done by removing at least two (2) of the plugs on the bottom and top of each Tube Header
Section. Internal Drum Inspection is made by removing the Inspection Plugs on the heads of the Steam Drum. Water
feed inlet should be Inspected every 6 months by removing the plug on the inlet fitting to Boiler Drum. Clean as
necessary. Note: always use a high temperature Teflon based anti-seize compound when reinstalling plugs. See
Bulletin 117 -1001 S&G.
14 TUNE-UPS: Overall boiler operation and burner condition should be evaluated as outlined and described on tune-up
sheets.
15 OTHER IMPORTANT MAINTENANCE: The Boiler should be regularly serviced and properly maintained in
accordance with the Operating, Daily Boiler Blowdown Instructions, Safety and Preventive Maintenance Sheets and all
other Maintenance Sheets as furnished in the Boiler Operation & Maintenance Manual.
W A R N I N G S
1. ONLY TRAINED AND KNOWLEDGEABLE QUALIFIED PERSONNEL SHOULD BE ALLOWED TO OPERATE,
SERVICE OR REPAIR THE BOILER. WEAR SAFETY GLASSES AT ALL TIMES.
2. ALWAYS SHUTOFF THE MAIN ELECTRICAL SUPPLY SWITCH(ES) BEFORE WORKING ON THE BOILER OR
CONTROLS. NEVER ATTEMPT TO WORK ON ANY PIPING OR PRESSURE PARTS WHEN THERE IS
PRESSURE IN BOILER. ALWAYS SHUTOFF THE BOILER AND BLOWDOWN TO ZERO PRESSURE.
3. NEVER PUT AN EXTENSION ON VALVE HANDLE FOR MORE LEVERAGE. DO NOT APPLY UNDUE FORCE ON
FITTINGS OR TO OPEN VALVES WHILE THERE IS PRESSURE IN BOILER. ANY PRESSURE PARTS AND
PIPING SHOULD BE PROMPTLY REPLACED ON INDICATION OF LEAKS, DETERIORATION OR AN UNSAFE
CONDITION. PROMPTLY REPLACE ANY FAULTY PARTS OR VALVES.
4. ALL STEAM VALVES AND BLOW-OFF VALVES MUST BE OPENED CAREFULLY AND SLOWLY. REPLACEMENT
OF ANY VALVES OR PRESSURE PARTS MUST COMPLY WITH THE CODE FOR STEAM PRESSURE STAMPED
ON THE BOILER.
5. NEVER BYPASS SAFETY CONTROLS. IMMEDIATELY REPAIR OR REPLACE FAULTY CONTROLS AND TEST
BEFORE PLACING BOILER IN OPERATION.
6. THE WATER INLET VALVE TO RETURN TANK SHOULD BE CLOSED WHEN BOILER IS NOT IN USE IF THERE
IS A POSSIBILITY OF WATER DAMAGE TO PROPERTY.
The Manufacturer and Parker Dealers are sincerely interested to cooperate with each field installation to assist in obtaining
the best in long life and satisfactory service deserving of the Parker equipment. Any additional instructions or assistance will
be gladly provided on request.

BOILER MAINTENANCE & WATER TREATMENT
It must be understood that every Steam Boiler system requires a proper Boiler Water Treatment Program with
regular water analyses, adequate regulated blowdowns, correct maintenance, periodic safety checks and periodic
inspection follow-up. All of these are necessary for long life and efficient boiler service. These are some of the
basic essentials in your boiler program:
1. Soft water should be used at all times to prevent scale build-up and tube stoppage. Test daily and regenerate
water softener when hardness exceeds 17 parts per million (or 1.0 Grain per Gallon).
2. Boiler water compound should be selected and regulated on the basis of actual water analysis. This
compound should have the proper chemicals to treat for: (1) hardness up to 5.0 GPG, (2) maintain a pH level
of 10.0 to 11.5 in the boiler water, (3) excessive oxygen by maintaining the Sodium Sulfite level between 40 to
100 ppm in the boiler water, (4) a protective metal coating material, and (5) other conditions found in the water
analysis. A Boiler compound comparable to PB677 is standardly recommended. When steam may come in
contact with potable water or food products for human consumption, a USDA approved compound, such as
PB633, is required. For Parker PB677, 633, 647, OS2 (Oxygen Scavenger) usage quantities and instructions
see Bulletin OS-125 and CPS-K-125-P.
3. The compound must be added in adequate quantities uniformly throughout the shift. An automatic chemical
feed system should be purchased or provided by your chemical supplier so these chemicals are induced into
the condensate holding tank or feedwater line as recommended by your chemical supplier. We recommend
these chemicals be introduced as far before the boiler as possible to also protect the feed tank and feed lines.
4. Regular Water Analysis should be made as often as possible but at least every 30 days to assure water
treatment is properly regulated. If there are indications of scale, corrosion, or any other unfavorable condition,
water analysis may need to be performed more often until condition is corrected. Record these figures (i.e.
Parker Bulletin 1001-C) for future reference. See Bulletin 1002 for instructions.
5. Partial blowdowns should be made in accordance with the Blowdown Instructions. The Boiler blowdowns
must be made sufficiently so that total dissolved solids in the Boiler water between 2600-3200 PPM (3600-
4200 micromhos/cm) and mud and sediment are removed from the boiler. The type of blowdown and period
between blowdowns can be extended only when the total dissolved solids in the boiler are maintained below
between 2600-3200 PPM (3600-4200 micromhos/cm).
6. Regular Internal Tube Inspections should be made every 60 days until the Water Treatment Program is
properly regulated. Thereafter, every 6-12 months or more often if an unsatisfactory condition is found. This is
done by removing at least two (2) of the plugs on the bottom and top of each Tube Header Section. Internal
Drum Inspection is made by removing the Inspection Plugs on the heads of the Steam Drum. Water feed inlet
should be Inspected every 6 months by removing the plug on the inlet fitting to Boiler Drum. Clean as
necessary. Note: always use a high temperature teflon based anti-seize compound when re-installing plugs.
See Bulletin 117 -1001 S&G.
7. The Return Tank and pump suction strainer should be inspected and flushed clean every 90 days or as
needed. This is important to prevent any sediment accumulation from causing stoppage, or damage to Pump
or Boiler.
8. Proper Grounding of the boiler is necessary if there is a possibility of electrolysis (a form of corrosion) and to
help maintain normal tube life. Periodic internal inspections are necessary to determine if the thin protective
coating has developed in the tubes. Proper grounding of the boiler requires driving a copper rod of 6’ or more
into the ground. Readings in excess of 35MV on ungrounded installations require grounding to prevent the
onset of a corrosion problem.
WARNING: DO NOT BE MISLED BY PURCHASING YOUR COMPOUND AT A CHEAPER PRICE OR FROM
A SUPPLIER THAT IS NOT FULLY COMPETENT TO PROVIDE YOU WITH INSTRUCTIONS,
WATER ANALYSIS AND FOLLOW-UP SERVICE NECESSARY FOR SATISFACTORY
RESULTS.
The Standard Boiler Warranty covers only original defects and does not cover the repairs resulting from a water
condition such as corrosion or scale. It's up to you and is your sole responsibility to see that a proper Water
Treatment and Maintenance Program are correctly followed at all times.

THIS IS THE SHEET THAT IS INCLUDED WITH THE WATER SAMPLE BOTTLES
INSTRUCTIONS FOR WATER SAMPLES
PARKER STEAM BOILERS
Every Steam Boiler installation must be properly supervised with a proper Water Treating Program and Blowdown Procedure. The
recommended method to initially determine the Water Treating Program is by an actual Analysis of the raw water supply, soft water,
return tank water, and boiler water. Regular Water Analysis should be made at least every 30 days to assure water treatment is
properly regulated. If there are indications of scale, corrosion, or any unfavorable condition, water analysis may need to be performed
more often until condition is corrected. We recommend a full service Chemical Program which includes a chemical feed system,
chemicals and a monthly on site analysis. If a month is missed from this schedule, forward a sample per the following instructions.
The purpose of these instructions is to inform the operator on the correct method of taking Water Samples so that the information on
the Analysis may be proper and accurate.
I. GENERAL INFORMATION:
A. Water Samples should be taken in a 4 to 6 ounce clean glass or plastic screw type medicine bottle.
Always rinse the bottle and cap thoroughly before taking sample and fill to the top with little or no air in bottle.
Always wear safety glasses.
B. Each Sample Bottle should be properly labeled with the following information:
1. Date: __________________________________________________________________
2. Distributor: ______________________________________________________________(if other than Parker Boiler)
3. Customer Name:_________________________________________________________

16. BULLETIN 1002-B
6C
II. METHOD OF TAKING WATER SAMPLES:
A. BOILER WATER: Take Samples from the try cock, sample valve or water glass drain on the Boiler Water
Column. WARNING! Always wear safety glasses when taking water samples.
USE CAUTION AND SAFETY AS FOLLOWS:
1. Before taking the Sample, make a partial blowdown or flush at the point where taking
sample so that it will be more representative of the Boiler Water.
2. Take the sample just before making the regular blowdown so that the concentrated
solids will be at maximum for determining necessity of any revision in the blowdown.
3. Hold bottle or container with long handle tongs and place securely over the valve
outlet. Open valve slightly being careful not to splash hot water outside of bottle. If
glass bottle is used, be sure bottle has been warmed and proper precautions taken
for safety. Keep hands and body at a safe distance and open valve just slightly so
water will not splash.
B. SOFTENED WATER: Should be taken initially and periodically if the Boiler Water does not test continuously
soft. Take at the soft water service outlet.
C. RAW WATER: Should be taken initially on each new installation and periodically if some problem or
change develops in the water source.
D. RETURN TANK WATER: Should be taken only if the Return Tank water is assumed to contain contaminates or relating
to some problem such as steam line corrosion. The sample can be taken from the
Return Tank drain line. Before taking the sample, let the line flush so that the sample
will be representative of the tank water.
NOTE: Water in the return tank should be 2/3 of the way up the internal well so the pump cannot empty the return tank and pull
in oxygen.
III. ANALYSIS REPORT:
When the Sample of water has been Analyzed, a report is supplied by the Laboratory to Parker Boiler Co. A detailed letter of
recommendation is then written to the customer, explaining the findings and if any revisions should be made in the use of
the Compound and the Blowdown procedures. Any questions regarding the reports or recommendations should be directed
to Parker Boiler.
Parker Boiler provides initial Water Analyses and Water Treating Recommendations to all customers without charge. Two water
Sample Containers for convenient mailing are furnished with each boiler and additional Containers will be gladly mailed on
request. A Charge of $10.00 for each Analysis is applicable only when using Boiler Compound not furnished by Parker Boiler.

MFB (METAL FIBER BURNER) GENERAL MAINTENANCE
The Parker Premix Metal Fiber Burner System should be checked and tuned by a competent personnel normally on a
yearly basis. Only trained and qualified personnel should install, start-up, operate, adjust, repair or maintain this boiler
equipment. The Parker Premix Metal Fiber Burner System is an extremely durable ultra Low NOx High Efficiency
Burner System incorporating a premixed blower mixer. This System offers very durable burners and outstanding
repeatability from year to year in terms of gas/air ratios, and NOx emissions.
In some situations dirt, dust, debris, etc. may accumulate on the burner surface and have the effect of increasing the
pressure drop through the burner surface slightly. These type of aberrations can be easily corrected by slight
adjustments of the burner system and or burner cleaning.
The following procedure summarizes the recommended servicing, maintenance and tune-up procedures for Parker
Premix Metal Fiber Burner Systems. Please note that it is quite important that large particles, dust, beads, etc. do not
enter the Burner System as this could create blockage of the Premix Metal Fiber Distribution System. The frequency of
maintenance required on the particular items on the Burner System is extremely dependent on environmental
conditions. In dusty, corrosive, or salt atmospheres more maintenance/lubrication is required.

I. PRELIMINARY ANALYSIS (REVIEW WITH OWNER)
A. CHECK THE OPERATING PRESSURE OR TEMPERATURE. Operate the boiler at the lowest pressure or
temperature that will satisfy the load demand not less than 130o
F for hot water boilers. This will minimize heat and
radiation losses. Determine the pressure or temperature that will be used as a basis for comparative combustion
analysis before and after tune-up.
B. CHECK OPERATING HOURS. Plan the work load so that the boiler operates only the minimum hours and days
necessary to perform the work required. Less operating hours will reduce fuel and other costs.
C. CHECK INSULATION. Check condition of (or absence of) appropriate insulation on all cabinet, steam pipes,
return tank, heat exchangers, storage tanks, etc. Lack of insulation will significantly increase fuel usage.
D. CHECK AIR SUPPLY. Sufficient fresh air supply is essential to insure optimum combustion and the area of
openings must be in compliance with local codes. Air openings must be kept wide open and clear from restriction.
Air openings must comply with the Uniform Mechanical Code. Insure air supply is from safe source.
E. CHECK VENT. Proper venting is essential to assure efficient combustion. Insufficient draft or over-draft
promotes hazards and inefficient burning. Check to be sure that vent is in good condition, sized properly and with
no obstructions.
F. AS IS COMBUSTION. Perform an AS IS combustion analysis with a warmed up boiler at High, Medium and Low
fire if possible. Insure blower modulating circuit drives from hi to low properly. Close all doors and windows in
boiler room, turn on any exhaust fans that may run at the same time as the boiler. In addition to print out from
Combustion Analyzer, also record:
1. Gas Pressure at blower inlet: High fire "W.C. Med fire "W.C. Low fire " W.C.
2. Premix Manifold Press: High fire "W.C. Med fire "W.C. Low fire " W.C.
. 3. Maxon Position: High fire Med fire Low fire
4. Maxon Amps: High fire Med fire Low fire
(Check for proper rotation)
5. Draft below draft hood or barometric damper:
High fire "W.C. Med fire "W.C. Low fire " W.C.
Preferred values are:
1) Draft hood: less than (- .02" W.C.)
2) Barometric Damper: (- .04 to - .06" W.C.) as a minimum.

COMMENTS:

19. TU-1146L
P3 0H7
With Item I, Section F conditions recorded make the following checks and corrective actions as necessary:
II. CHECKS & CORRECTIONS
A. CHECK FOR CLEAN BOILER TUBES & HEAT TRANSFER SURFACES. Internal build-up of sediment
and scale on the heating surfaces creates an insulating effect that quickly reduces efficiency. A 1/16" of scale will
reduce efficiency and increase operating costs in excess of 14%. External build-up of soot and sediment will have a
comparable effect. Excessive fuel cost will result if the boiler is not kept clean. Clean tube surfaces, remove scale
and soot, assure proper boiler water flow and flue gas flow.
COMMENTS ON INTERNAL & EXTERNAL TUBE CONDITION:
B. CHECK BOILER WATER TREATMENT & BLOWDOWN PROGRAM. Soft water and the proper Boiler
Water Treatment must be uniformly used to minimize scale and corrosion. Daily flushing and the proper blowdown must be
employed to eliminate sediment and scale build-up on a steam boiler.
COMMENTS:
C. CHECK FOR STEAM LEAKS. Repair all leaks immediately as even small leaks at high pressure quickly add up
to considerable fuel and water treatment losses. Be sure there are no leaks through the blow-off, drains, safety
valve, by-pass lines or at the boiler feed pump.
COMMENTS
D. CHECK METAL FIBER BURNER & PREMIX SYSTEM CONDITION
1. Remove boiler doors and observe normal light off sequence. Insure all burners light off smoothly and flame
carryover is good.
2. Insure boiler drives to low fire for pilot ignition if appropriate for that model. NOTE: Not lower than 5-6 on
Maxon (for boilers greater than 1,500,000 BTUs.) Most systems employ a purge period and the pilot trial for
ignition occurs at low fire.
3. Insure purge time is correct.
4. Insure that all burners are straight and level. Insure that no holes, cracks or warps have developed on top or on
sides of burner or on mating flanges. Insure the entire surface has even flame distribution, thru all firing rates.
5. Look for dirt or metal flakes on burner surface.
6. Burner surface dirt, dust, metal flakes, etc. should be cleaned off of burner surface. Use air, soft rag or soft
brush to dust burners off. It is also effective to vacuum the burners with a strong vacuum with a soft
attachment. Do not use wire brush. If burners are still dirty after above procedures, the burners can be
removed and washed. If CO & NOx cannot come into conformance it is likely the burners need cleaning.
7. Check carryover tube condition and mounting. Insure carryover is proper from tube to tube.
8. Insure premix manifold and piping have no gas/air leaks and no damage or warpage has occurred.
9. Check all bolts and nuts from transition from pipe to MFB burners. Insure no deformations have occurred.
10. Repair all defective or questionable items.
COMMENTS ON BURNER CONDITION: ____________________________________________________________

E. BLOWER MIXER CHECK
1. Check rotation
2. Check motor and casing bolts, tighten if required.
3. Check impeller hold down Allen screws for tightness, insure impeller is firmly mounted to shaft.
4. Insure impeller is centered in casing.
5. Check for smooth rotation, no rubbing should occur.
FOR SPECIFIC TUNE UP PROCEDURES REFER TO CORRESPONDING SUPPLEMENTARY START
UP INSTRUCTIONS FOR PARTICULAR BURNER SYSTEM. FOR SYSTEM 1, MAXON "PL"
SYSTEM SEE FOLLOWING INSTRUCTIONS.
6. It should be insured that the Maxon Ratio Valve does not drive to a position of less than 5 at the low fire and light
off positions. (Applicable for boilers greater than 1,500,000 BTU.) For low fire positions lower than this consult
factory.
7. It should also be insured that the Maxon Ratio Control Valve has stainless steel shafts installed. Please note that
Parker Boilers shipped before 9/1/95 may be provided with a carbon steel shaft riding in the cast iron housing.
This situation may create corrosion and shaft binding. Maxon's solution to the problem has been to change this
shaft to a slightly smaller diameter stainless steel shaft with O-rings to retain grease and a groove recessment in the
shaft to also retain grease at the point where lubrication is required. It should be insured on jobs where tune-ups
are accomplished that shafts have been changed to stainless steel and lubricated. It is critical that both the gas and
the air shaft be changed and lubricated so it is insured that neither the gas or air shaft will bind.
8. Lubrication: The gas and air shafts should be lubricated either yearly or more often to insure continued smooth
operation. In corrosive atmospheres i.e. near the ocean, lubrication should occur more frequently. Maxon shaft
assembly should be disassembled to allow shaft removal, see Maxon literature. Sand or buff shaft smooth as
required, grease and reassemble. Insure positioning of shaft upon reassembling is identical to previous positioning.
(Note: Allen screw countersinks on air shaft).
9. As part of the check out process for the Maxon Ratio Valve it is recommended that when the quadrant is removed
the gas shaft be compressed all the way and it should be insured that the spring return on the gas shaft is working
properly and that this shaft will not bind at the high fire position.
10. Check that blower mixer drives from hi to low properly and does not attempt to overdrive stops.
11. Check linkage and Maxon cam for tightness.
12. Check amps on Maxon blower mixer. Record with combustion readings.
COMMENTS:
F. SAFETY CHECKS
1. Check gas line for leaks.
2. Check boiler vent.
3. Insure combustion air is from safe clean source and per Code.
4. On Steam Boilers Check tubing to pressure controls to confirm clean tubes and accurate pressure readings.
5. Test primary and secondary low water controls.
6. Check operating, modulating and limit controls (Pressure, temperature, high and low gas and flue gas spillage).
Operating Control PSI High Limit PSI
7. Check pilot safety shut off operation.
8. Check fan air switch.
9. Check electrical starter interlock to insure burner shuts off with loss of power to blower.
10. Check safety valve pressure and capacity to meet boiler requirements and trim pressure. Lift relief valve with
Customer pre-approval and Customer pre-arrangement to pay for replacement if required, or insure that Customer
will test relief valve on a monthly basis. It is important the valve be re-seated properly.

A) Regulator adjustment
B) Maxon cam adjustment. By decreasing the amount of fuel by a gas pressure reduction or by closing the Maxon
Butterfly valve (i.e. screw out on Maxon Allen cam) the O2 level at that firing position will be increased and
the NOx decreased. Refer to Parker and Maxon start-up instructions for Maxon adjustment. If gas pressure is
increased or Maxon Butterfly opened, opposite effect occurs.
C) By decreasing the fuel flow the flame may tend to blow out and CO may result. Increase fuel to alleviate CO.
2) Draft adjustment: By decreasing draft on boiler O2 levels will be lowered and NOx increased. By increasing
draft opposite effect occurs. Add weights to barometric damper to increase draft. Always check high fire heat
roll out around cabinet bottom when setting draft.
3) Determine the required emission and adjust as required.
C. When adjusting a boiler it is important to insure that the burner does not sit in low fire for prolonged periods of
time. This can be accomplished by adjusting either the L91 Pressure Trol, the Modulating Control or Hi-Low
Control on the boiler to insure that the boiler will purge, light, drive towards high fire, return towards low fire and
then shut off. If the boiler does sit for prolonged periods at low fire in the radiant mode (rich fuel mixture, High
NOx) burner damage may occur:
D. Perform combustion analysis with a warmed up boiler at High, Medium and Low fire if possible. Adjust for
maximum efficiency lowest oxygen level while still holding NOx and CO below the terms of the Permit to Operate
or as appropriate. Look for blue flame not orange, radiant glowing. In addition to print out from Combustion
Analyzer, also record the following, note approximate sample settings (note sample point for flue gas is below draft
control.

27. GENERAL BASIC INSTALLATION INSTRUCTIONS GBI 101-5
PARKER BOILER CO. STEAM BOILERS 3C
For a proper installation and in order to receive the best in operating life and efficiency from your Parker Steam Boiler, it is essential to
follow the Manufacturer's Minimum Standards and all the Requirements of State and Local Codes. Before installing the Boiler carefully
review these General Basic Installation Instructions, the specific Installation Instructions, the Installation Drawings, and the Boiler
Room Floor Plan Drawings as these instructions illustrate the Recommended Installation Procedure.
CAUTION: ALL INFORMATION ON THESE SHEETS IS IMPORTANT. Failure to give all factors proper consideration may result in
an unsafe and inefficient installation. Manufacturer's Recommendations are a Minimum Standard for Satisfactory Installation. The
installation must also follow all Safety Codes including the ASME Boiler and Controls Codes, National Fuel Gas Code (NFPA 54/ANSI
Z223.1), National Electric Code (NFPA 70), Uniform Codes and other applicable National, State, Local and Servicing Gas Supplier
Codes. Only trained and qualified personnel should install, startup, operate, adjust, repair or maintain this boiler equipment.
Parker Boilers are equipped with Code required safety controls which will automatically shutdown boiler when unsafe conditions are
sensed. Customer must provide adequate supervision when service interruption or freeze-up presents a problem. Boilers, tanks,
pumps and piping, in areas subject to freezing conditions must be drained or protected. All components in the steam system under
pressure must be rated for a pressure at least equal to the Boiler Maximum Allowable Working Pressure or a Pressure Reducing Valve
and additional Low Pressure Safety Valve must be installed. If a hot water storage tank is used, it must be equipped with a safety
relief valve. A Combination Temperature and Pressure type is recommended for domestic or potable water supply heating.
I. SELECTION OF A BOILER:
THE FOLLOWING FACTORS SHOULD BE GIVEN VERY CAREFUL CONSIDERATION IN SELECTION OF THE BOILER:
(1) SIZE OF THE BOILER: The Boiler must be of adequate capacity to handle the maximum hourly load of the particular application,
plus radiation losses. It is considered good practice to install a Boiler of sufficient capacity to handle future expansion
requirements or to allow space for an additional future Boiler. On critical or large installations, it is recommended to install two or
more Boilers, each sufficient size to handle the minimum load so that the operation is not interrupted when one of the Boilers is
being serviced. If the load is not definitely known, it is advisable to consult the boiler manufacturer or competent personnel to
determine the load.
(2) APPROVED TYPE QUALITY BOILER: The Boiler should be a quality, approved Boiler, manufactured and furnished in full
compliance with the Safety Requirements of the A.S.M.E. Code. The Boiler selected should be safe, efficient and easy to
maintain to provide economical and reliable service. The Parker Sectional Bent Water Tube is highly recommended as it provides
one of safest, most economical and long life systems that is easy and inexpensive to maintain.
(3) TRIM AND CONTROLS: The Boiler should be equipped with fully automatic controls to provide automatic and safe operation. All
Trim and Controls should comply with Local Code, the State Safety Orders, the A.S.M.E. Codes and Underwriters' Laboratories.
A flame safeguard, operating control, high limit, primary and secondary low water cutoffs and dual safety shutoff fuel valves are
considered essential on all Boilers.
(4) PROPER BOILER SPECIFICATIONS: The complete Boiler Specifications should be thoroughly reviewed for the proper working
pressure required, the most economical fuel available and proper electrical requirements.
II. INSTALLATION AND OPERATING PERMITS:
Before installing the Boiler be certain that all Permits for the installation and operation of the boiler have been taken out and installation
conditions approved by the Building Inspection Jurisdiction. Permits are usually required on the Boiler and Utilities including Gas,
Electrical, Water, Vent and Plumbing Connections. Some States and Cities require a Field Inspection by a State or National Board
Commissioned Boiler Inspector and a "Permit to Operate" issued before the Boiler is placed in service. Heavy Penalties and Unsafe
Conditions may result when these Permits and Inspections are not obtained from the Inspection Jurisdiction. If Local Codes or
Insurance Carrier require additional or special controls, the boiler manufacturer should be consulted so that the equipment can be
furnished as required.
III. BOILER ROOM AREA AND BOILER BASE:
Consult with Local Codes for Boiler Room and Fire Resistive Separation if required and refer to Paragraph IV. The Standard Boiler is
not recommended for outside installation without providing the required protection from weather and drafts. An approved floor sump or
drain must be provided in the Boiler area to accommodate safety valves, boiler drains and leaks from any source. Floors should be
properly planned and graded to the floor sump or drain to prevent water damage.
When Boiler Rooms are necessary, two access doors are always recommended and normally required. The larger door should be
adequate to permit the Boiler to be moved in and out without disassembly. Location of the Boiler Room should be selected as
conveniently near the load as possible with all installation factors considered. Do not install the boiler in any location where flammable
liquids or vapors are likely to be present or drawn. Keep the area around the boiler free of combustible materials, gasoline, paint,
thinner, solvents and other flammable liquids and vapors.
Adequate space should be arranged for the Return System, Blowdown Tank and the Water Treatment Equipment. Boilers can be
installed in smaller areas than the recommended size but the area should never be less than the minimum shown on the Boiler Room
Specification Sheet.
BOILER MUST BE INSTALLED ON A NON-COMBUSTIBLE FLOOR preferably of concrete and properly designed to support the
required weight and to protect against any Fire Hazard. Combustible floors require an Approved Fire-Proof Base, consult
Manufacturer. Do Not install on wood, carpet, vinyl tiles, black-top or on concrete with wood or electrical conduit imbedded or directly
underneath without consulting Manufacturer for an approved base.

IV. BOILER CLEARANCES:
MINIMUM UL LISTED BOILER CLEARANCE TO COMBUSTIBLES CONSTRUCTION (Atmospheric Nat. Gas Only): Cabinet Sides
and Rear: 12"; Cabinet Top: 48"; Single Wall Chimney Connector for Models with Barometric Damper: 12"; Single Wall Vent
Connector for Models with Draft Hood: 6"; Steam and Hot Water Piping: 1".
MINIMUM UNLISTED BOILER CLEARANCE TO COMBUSTIBLES CONSTRUCTION (Unlisted & Power Burner Models): Cabinet
Sides and Rear: 18"; Cabinet Top: 48"; Single Wall Chimney Connector for Models with Barometric Damper: 18"; Single Wall Vent
Connector for Models with Draft Hood: 18"; Steam and Hot Water Piping: 1".
RECOMMENDED CLEARANCE FOR ACCESS: Boiler must also be installed with adequate clearance for Maintenance, Repair and
Inspection Access. Passageways and Inspection Doors: 18" (2/3 Cabinet Width in front of one Inspection Door on the 30-150 H.P.
Boilers); Controls: 24"; Boiler Control Panels: 30" Additional space may be required by the Local Inspection Jurisdiction.
V. AIR SUPPLY:
The Boiler requires fresh air for safe operation and must be installed so there are provisions for adequate combustion and ventilation
air. In confined rooms (rooms whose volume is less than 50 cu.ft. per 1000 BTU aggregate input) or unconfined boiler rooms of tight
construction, two permanent air openings shall be provided, one within 12" of the top and one within 12" of the bottom of the boiler
room.
AIR SUPPLY FROM OUTSIDE BUILDING: If the boiler room is confined or the building is of tight construction, openings shall be
provided that communicate freely with outdoors. The two openings should have a total free area of 1 sq.in. for each 1000 BTU of input
if attached to horizontal ducts; or a total free area of 1/2 sq.in. for each 1000 BTU if attached to vertical ducts or connected directly
through an outside wall. Consideration should always be given to the blocking effect of louvers in determining total free area. Wood
louvers may be assumed to have 20-25% free area and metal louvers and grills to have 60-75% free area.
AIR SUPPLY FROM INSIDE BUILDING FOR CONFINED ROOMS: The two openings should have a total free area of 2 sq.in. for each
1000 BTU of input communicating directly with an unconfined space with adequate infiltration.
In hot climates additional ventilation should be provided to maintain reasonable temperatures in boiler room. Always leave adequate
clearance around the base and legs of the Boiler so that air freely enters the combustion area. Be certain that additional air supply is
provided if there are exhaust fans or other equipment installed which draw air from the boiler room. Air supply should be provided from
a non-hazardous and clean source so that no flammable vapor, lint or dust is admitted to the boiler room. THE BOILER AIR SUPPLY
MUST BE ISOLATED FROM ANY SOURCE OF CORROSIVE CHEMICAL FUMES SUCH AS PERCHLORETHYLENE, ETC. Consult
Local Code or Manufacturer for any unusual conditions.
VI. VENT:
A. COMBUSTION VENTS:
The proper Boiler Venting System is required to assure the necessary draft for efficient combustion and to develop a positive flow
adequate to convey all products of combustion safely to outside atmosphere above the building. All venting must be in conformity with
accepted engineering practices, to the Manufacturer's Minimum Standards, and in compliance with the Local Code in every respect.
All Vent Systems should be installed in a safe workmanlike manner, properly supported and joints secured to prevent leakage. Never
drill holes or screw metal screws into double wall vent. DO NOT SUPPORT THE WEIGHT OF THE VENT ON THE BOILER.
The Boiler Vent should preferably be circular and of metal, installed to Local Code Specifications for Vent Material and all Installation
Conditions. Do not reduce vent size or connect more than one appliance to a single vent unless in compliance with good safe
accepted practices and with approval of the Building Inspection Authority. The Main Vent should run straight up from the Boiler and if
horizontal runs are necessary, these should be as straight and direct as possible with a minimum rise of at least 1/4" per lineal foot.
Long horizontal runs are not recommended and must not exceed 75% of the vertical height of the vent above the connector. Proper
vent clearance must be provided from any combustible material, wall openings or exit way. In cold climates, outside vents must be
properly insulated.
The Draft Hood or Barometric Damper must be installed directly on the Boiler Vent Outlet as shown and in the same room with the
Boiler. Do not terminate vents near windows, doors, ducts, air conditioning or air supply fans which might pick up flue products
exhausted from the boiler room and return them into the building, causing a serious health hazard to occupants. An unrestricted full
size vent cap should be installed on the top of the stack to protect from wind and rain.
When installation conditions require special vents or draft inducers, the design and safety controls should be approved by Competent
Combustion Personnel. When a draft inducer is required, always install a suitable draft switch and wire this into the boiler control
circuit to prevent the boiler from firing unless the draft is proven. If a draft inducer is used, the boiler requires a positive pressure type
chimney from the outlet of the inducer to the termination. In planning the vent installation, carefully review these Instructions and
consult with the Building Inspection Authority on the Local Code for the Required Approval.
These are the Manufacturer's Recommended Minimum Standards but all installation materials and conditions must conform to the
Local Code Requirements and good safe engineering practices for the particular installation.

VI. VENT - Continued
When installation conditions require special vents or draft inducers, the design and safety controls should be approved by Competent
Combustion Personnel. When a draft inducer is required, always install a suitable draft switch and wire this into the boiler control
circuit to prevent the boiler from firing unless the draft is proven. If a draft inducer is used, the boiler requires a positive pressure type
chimney from the outlet of the inducer to the termination. In planning the vent installation, carefully review these Instructions and
consult with the Building Inspection Authority on the Local Code for the Required Approval.
These are the Manufacturer's Recommended Minimum Standards but all installation materials and conditions must conform to the
Local Code Requirements and good safe engineering practices for the particular installation.
(1) VENTS FOR ATMOSPHERIC GAS FIRED BOILERS WITH DRAFT HOODS:
PARKER UL LISTED GAS FIRED BOILERS EQUIPPED WITH DRAFT HOODS ARE APPROVED FOR INSTALLATION WITH TYPE
B GAS VENT. Type B Vents should always be installed in accordance with the Manufacturer's Instructions. Listed Double Wall Vent
is preferred and must be used in any attic, concealed space and for any combustible floor, ceiling or roof penetration. Vent connectors
should be galvanized steel minimum 24 gage thru 12" diameter and 22 gage on larger diameters. Elbows used as vent connectors
may be one gage lighter. The Vent must terminate at least 2 feet above the roof or any part of the building within 10 feet. If single wall
metal pipe vent is allowed as the main vent by the Local Inspection Jurisdiction, it should be a minimum 20 gage galvanized material
and used only for runs directly from the boiler area to the outside. Single wall metal pipe vent installed through a combustible roof or
wall must be guarded at the point of passage with the required ventilated thimble or the combustible material cut away to provide not
less than 18" clearance (6" UL Listed Models) on all sides of the vent. With full size vent installed, no spillage should be experienced
at the draft hood. A minimum draft of .01" W.C. negative pressure should be experienced above the draft hood. If the draft below the
draft hood registers in excess of .02", Competent Combustion Personnel or Gas Company Engineer should be consulted for
combustion test and adjustments to control draft for best efficiency. Draft Hood equipped LPG and other special Models that are not
UL Listed also have stack temperatures below 400°F and are safe for connection to a Type B Vent per Manufacturer's
Recommendations; however some Jurisdictions require suitable chimneys on all unlisted equipment [see Parg. (2)].
(2) CHIMNEYS FOR BOILERS WITH BAROMETRIC DAMPERS:
ALL BOILERS EQUIPPED WITH BAROMETRIC DAMPERS MUST BE CONNECTED TO SUITABLE CHIMNEYS. These Boilers may
be classified as Residential-Type, Building Heating or Low Heat Appliances with flue gas temperatures below 600°F. A UL Listed
Factory Built Chimney (Minimum Residential Type or Building Heating Appliance Type for Negative Pressure) should be installed in
accordance with the Manufacturer's Instructions. Chimney connectors shall be galvanized steel minimum 22 GA thru 12" diameter, 20
GA thru 16" diameter, and 16 GA over 16" diameter. The chimney must terminate at least 3 feet above the roof and 2 feet above any
part of the building within 10 feet. When a chimney extends through any story above that in which the boiler is located, including drop
ceilings and crawl spaces, it should be enclosed within continuous non-combustible construction of the appropriate fire resistive rating
with a minimum 12" clearance for access. If a single wall metal chimney is used it should be steel minimum of 10 GA. Support for this
type chimney should be independent of building construction with the load transferred to the ground. Single wall metal chimney
installed through a combustible roof or wall must be guarded at the point of passage with the required ventilated metal thimble or the
combustible material cut away to provide not less than 18" clearance (12" UL Listed Atmospheric Gas Fired Models) on all sides of the
chimney. The Red Stops on the Barometric Damper should be removed on gas fired boilers but must remain in place on all oil and
combination fired boilers. When a Flue Gas Spillage Switch is furnished on gas fired boilers it is pre-wired but must be properly
mounted above the damper as described on a separate bulletin. On all jobs, particularly high altitudes or restrictive vent conditions, it
is advisable to call in Competent Combustion Personnel to make a Complete Combustion Test for setting of draft to obtain best
efficiency and safety. Draft should be set for best efficiency as low as possible without CO or Smoke in the flue gas.
(a). ATMOSPHERIC GAS FIRED MODELS: With full size chimney installed to proper height never less than 5', a min. draft of not
less than .02 to .04" W.C. negative pressure should be experienced below the barometric damper.
(b). POWER BURNER MODELS: With full size chimney installed to proper height, never less than 12', a minimum draft of not less
than .04 to .06" W.C. negative pressure should be experienced below the barometric damper.
B. CONTROL & VALVE VENTS:
On certain Systems, the gas pressure regulator and other gas components require separate vent lines to outside atmosphere. These
controls are Marked when vents are required and they must be piped full size outside the building to a Safe Point of Discharge away
from all personnel, ignition sources and air intakes. Gas pressure regulators above 1" size (above 3/8" size for medium or high
pressure gas service) must be piped outside.
Controls requiring atmospheric vents such as gas pressure switches and gas pressure regulators that are not equipped with integral
vent limiters, must be piped outdoors to a safe point of discharge. Do not vent into combustion chamber. A means must be provided
at the termination point to prevent a stoppage of the line by foreign material, moisture, or insects. In the event of diaphragm rupture,
gas will be discharged from vent.
Atmospheric vent lines must not be connected to any gas vent, bleed or relief line. Atmospheric vent lines, when manifolded, shall be
connected to a common vent line having a cross sectional area not less than the area of the largest vent line plus 50 percent of the
areas of all the additional vent lines.
NORMALLY OPEN FUEL VENT VALVE (if furnished) is sized in accordance with the following chart of nominal pipe sizes:
FUEL LINE SIZE: Up to 1-1/2" 2" 2-1/2 to 3" 4"
VENT LINE SIZE: 3/4" 1" 1-1/4" 2"
